Mr Rich said there is “uncertainty” about the weather pattern into next week but said the jet stream looks like it will head east into the UK, bringing unsettled weather for a time.

He added: “But as it clears away high pressure is likely to build its way back in.”

The Met Office also warned the UK could be “turning warmer once again” in the last week of August as an area of high pressure responsible for the summer heatwave takes hold on the UK.

Met Office meteorologist Simon Partridge said: “As we head back into the weekend, the jet stream moves further north – warmer conditionsthenare bringing in across the whole of the UK as we head for the weekend itself.

“So, the outlook for this week is a bit of a mixed bag. We are staying generally on the dry side, it will be fresher mid-week and that will lead to some chilly nights.

“But by the time we reach the weekend things are turning warmer once again.”

UK weather charts also indicate that temperatures could hit as high as 20C next Sunday before nudging 30C during the first week of September.
